Hi thanks for contacting HCM... First I would like to suggest you to avoid stress....as you are taking antidepressant ... Behavioural counselling therapy can be taken from psychiatrist ... Feel brain with positive thought... Regular exercise and yoga helpful... Second for your allergic condition consult good allergy specialist doctor for it... Wear mask while driving ... Keep exposure to dust and smoke minimum. Improve immunity by healthy and balanced diet with more fruits .. If doctor feel then antioxident tablets can be given ...Immunotherapy also helpful. Steam inhalation done two times daily... Take care
